Preface This book is arranged for the use of theL udlow Textile School. It shows by practical illustrations and examples how the different arithmetical processes are applied to mill work in this particular branch of the textile industry. The arithmetic is not intended to take the place of a complete arithmetic but at the same time a complete set of abstract examples are arranged according to grade and the concrete examples are extremely practical. The general necessity for an early understanding of decimals and proportion caused the placing of those matters at an early part of the book. Fractions have been treated in detail although they are used to a limited extent in the mills. In many cases the language used is that of the mill, consequently some words, usually explained in the notes, have other than the generally accepted meanings. Only the calculations in general use in theL udlow Mills, which have been tested practically, are included in the chapter on General Mill Work. The explanations have been made as simple as possible Later, it is intended to publish a school description of the various processes of manufacture in vogue in the jute and hemp industry which will contain a number of more advanced problems. Some of the examples in this book have been taken from the following arithmetics, Bradbury andE aton s, Thompson s, Smith s, and Wentworth s. Other authorities consulted were Carter, Sharp, and Leggatt. As this is the first attempt to publish an arithmetic relating to this particular branch of the textile industry, any suggestion for improvement will gladly be received.
